Description
Technical field
The invention belongs to railway track detection field, more particularly to a kind of railway heavy showers amount unmanned plane real-time intelligent measurement
Method and system.
Background technology
If Along Railway section is by serious mud-stone flow disaster, by entail dangers to traffic safety.Under intense rainfall condition,
The sighting distance of train operator seriously reduces, and is being difficult dangerous situation in front of discovery in the rain greatly.Meanwhile the mud-rock flow as caused by heavy rain, massif
Come down and serious harm is formed to railway bed.Chinese Railway passenger casualty accident --- Chengdu-Kunming railway the most heavy in history
Train falls down from the bridge accident, and cause of accident is that heavy rain triggers mud-rock flow to destroy by rush of water railway bridge.Modern architecture in Japan provides that 1h precipitation exceedes
25mm trains start to guard against, and 1h precipitation is run up to train speed limit 170km/h during 40~45mm.Advised according to China railways department
Fixed, 1h rainfall reaches Storm Rainfall Standard, need to start speed limit warning.《Regulations of railway technical operation》The 347th article of (high-speed railway part)
Regulation, rainy weather is met, when emphasis flood control location 1h rainfalls reach 45mm and the above, train speed limit 120km/h；1h rainfalls
Amount reach 60mm and more than, train speed limit 45km/h.
In order to reduce the harm caused by heavy showers is runed high-speed railway, in recent years, the railway including China is big
State begin to focus in grind build a kind of novel railway rainfall in real time monitoring and early warning system, such as company of JR East Japan Railways rainfall monitoring

The rainfall gauge and railway anti-disaster rainfall monitoring system of measurement》(the patent No.：201210333228.3).The work of this kind of early warning system
Mechanism is similar, is that landslide, mud-rock flow and crag, falling rocks or avalanche location etc. easily occurs in hard and dangerous mountain railway to easily cause at disaster
Institute's installing rainfall gauge, monitor hourly rainfall depth and continuous rainfall.When hourly rainfall depth and continuous rainfall exceed setting,
Alarmed in track division and regional dispatching institute, alert levels are set according to the size of hourly rainfall depth and continuous rainfall, are set
Foundation mainly according to the statistics of historical disaster situation, establishes rainfall-subgrade stability state model, to the row of different model
Car carries out Real-Time Scheduling commander under different automatic Railway Condition/regions and rainfall rank.Although above-mentioned this railway heavy showers early warning
Technology has started to come into operation, but the early investment construction cost of this early warning technology and the technical maintenance expense in later stage are all very
Height, and early warning blind area be present.Railway department is for the purpose of safety, it has to installs number as much as possible in whole piece railway line
The very huge rainfall monitoring station of amount, because only that so can just accomplish as intensive as possible to this Along Railway rainfall realization
Rain collection and covering.But theoretically, as long as not accomplishing to be provided with whole piece circuit at unlimited rainfall monitoring station, then this
Early warning technology scheme of the kind based on Along Railway rainfall monitoring station unavoidably will be in some railways for being fitted without rainfall monitoring station
Early warning blind area be present in region.
